EAP-TTLS is an EAP method that provides additional functionality
beyond what is available in EAP-TLS [RFC2716bis]. In EAP-TLS, a TLS
handshake is used to mutually authenticate a client and server. EAP-
TTLS extends this authentication negotiation by using the secure
connection established by the TLS handshake to exchange additional
information between client and server. In EAP-TTLS, the TLS
handshake may be mutual; or it may be one-way, in which only the
server is authenticated to the client. The secure connection
established by the handshake may then be used to allow the server to
authenticate the client using existing, widely-deployed
authentication mechanisms. The authentication of the client may
itself be EAP, or it may be another authentication protocol such as
PAP, CHAP, MS-CHAP or MS-CHAP-V2.
Thus, EAP-TTLS allows legacy password-based authentication protocols
to be used against existing authentication databases, while
protecting the security of these legacy protocols against
eavesdropping, man-in-the-middle and other attacks.
EAP-TTLS also allows client and server to establish keying material
for use in the data connection between the client and access point.
The keying material is established implicitly between client and
server based on the TLS handshake.
This document describes EAP-TTLSv0; that is, the original version 0
of the EAP-TTLS protocol, which has been widely deployed.
